SHEET-.METAL en Application filed November To all wkom z't may concern:

Be it known thatI, JAMES W. MQNEIL, a subject of the King of Great Britain, and resident of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Sheet- Metal Barrels, of which the following is a specification.

This'invention relates to improvements in j sheet metal barrels and has for one of; its. objects to provide a strong and durable bar rel which may be easily manufactured ofthin sheet metal and the parts of which may be easily assembled.-

In the accompanying drawings: 1

Fig. 1 is a side elevation of a barrel embodying the invention;

Fig.2 a plan view of one of theblanks from which staves are formed;

Fig. 3 a plan view of the barrel;

Fig. 4 a vertical transverse section on the line IV-IV of .Fig. 3;. f

Figs. 5 and 6 are detail. vertical sectionalv views showing the manner of forming the chimes of the barrel; Fig. 7 a fragmentary perspective view'of one of the stave-locking strips;

Fig. 8 a detail horizontal sectional .view showing the manner of assembling the staves and locking strips; and

Fig. 9 a detail perspective view showing the manner of interlocking the staves and locking strips.

' Thebody is formed from a plurality of staves each of which is curved in transverse section and bilged outwardly longitudinally of the staveso as to form a bilged barrel bodywhen the staves are assembled edge to edge.- Each of the staves 1 is formed with inwardly extending edge flanges 2 which project radially into the interior of the body when the staves are assembled. Each of the flanges 2 is provided with a plurality of vertically spaced lugs or tongues 3 formed integrally with'the flanges. Each stave may also be provided with reinforcing rib 4. extending longitudinally of the stave midway between the side edges of the stave. The reinforcing rib on each stave is formed by folding the body portion of a staveforming blank along three lon 'tudinally extending lines of folds 5, 6 and indicated in dotted lines in Fig. 2, to produce a double-walled inwardly projecting rib. The edge flanges 9.1920. serial No. 424,922.

2 are formed by folding the blank along longitudinal flines dotted lines" in-Fig. 2. v

Each stave blank is formed at each end with achime portion 9 beyond the ends of.,

the flange s'2, each of the chime portions 9 being cut away as shown at 10 to permit the formation of the reinforcing ribs 4 on the. I i stave without forming ribs in the chimes 9.

It will be obvious that when the blank shown in Fig. 2 1s folded to produce the ribs 4, the ad acent vertical edges of the cut away portion 10 will be brought together. When the blank shown in Fig. 2 is pressed into shape. to form a stave the chime-forming portions 7 9 are bent' slightly outwardly along the dotted lines 11 so that said-portions 9 will form cylindrical chimes at each end of the' barrel when the staves are assembled.

In assembling a barrel the staves are arranged edge to edge with the side flanges of each two adjacent staves abutting against each other as shownin Fig. 8. Sheet metal locking strips 12 of1channel form are then slipped .upon each pair of abutting stave flanges 2. -Each of the locking strips 12 is curved longitudinally to correspond with the curvature of the bilged body of the barrel and is cut away at intervals to form a series of slots orl apertures 13 in the base of the channel strip. The locking strips 12 extend from end to end of the flanges 2 on the staves each locking strip embraces one pair of abutting stave' flanges 2 throughout the width and length of the flanges, the outer edges of each. strip engagingagainst the in through the openings 13 in the locking strip vwhen the strip is slipped-on the flanges and and the depth of the channels in the strips is the same as the width of the flanges 2-so that are'then bent laterally in opposite directions flat against opposite sides of the locking strip, as shown more clearly in Figs. 8' and -9. As each locking strip embraces abutting edge flanges on twoadjacent staves itwill lateral separation'of the staves, and as the lugs 3 extend through the openings 13 in the locking strip andare bent round upon the outer. sides vof theystrip it will beseen that'the lugs 3' and, locking strips 12 will be seen that thelocking strips will'prevent prevent relative radial movement between I of fold 8 indicated in.

the staves either inwardly or outwardly and also prevent relative vertical movement between the staves.

To form the chimes of the barrel, sheet metal hoops 14 are slipped inwardly inside the extensions 9 of the staves at each end of the barrel body against the ends of the edge flanges 2 of the staves, and-said extensions 9 are then bent laterally and inwardly about the hoops 14 as shown in Fig. 6 to form a smooth cylindrical chime at each end of thebarrel. Two sheet'metal'hoops 15 are then slipped upon the exterior of the barrel body from opposite ends of the barrel until they\fianges on the staves being bind tightly on thebarrel body and are then locked in position by pressingportions of certain of'the staves outwardly to form locking shoulders or beads 16 on the exterior ,of the body against which theedges of the Two chime hoops 17 are then placed about hoops nearest the ends of the body engage.

1 the exterior of the chimes of the barrel.

The hoops 17 are formed of thin sheet metal 7 and preferably provided with outwardly flaring skirt portions 18 embracing the ends of the body portions of the staves.

Cup-shaped sheet metal heads 20 fit within the chime portions of the barrel body and seat against the adjacent ends of the stave flanges 2. The upper edge of the circular side wall of each head is rolled to form an outwardly projecting flange orhead 21 which overhangs the outer edge of the chime of the barrel and rests thereon and also rests against the upper edge of'the chime hoop It. The heads maybe locked in-place in 5 any suitable manner. For this purpose I have shown staples 22 which are driven inwardly through hoops 17 and 14, the chime portions 9 of the staves which are bent about the internal hoop 14, and then through the side wall of the head and clenched. If desired each head may be braced or reinforced by asheet metal spider comprising two bowed sheet metal members 23 fastened together midway their ends by a rivet 24 and having their opposite ends fastened to the head and the barrel body by the staples 22, as shown in Figs. 3 and 4. The head reinforcing spiders will prevent the heads from bulging, outwardly endwise of the-barrel.

It will be observed that the stave parts of the barrel are of simple construction, may be readily formed of thin sheet metal. and may be easily and quickly assembled. it will also be observed that by forming the chime portions of the barrel in the manner above described very strong chimes are produced which are not likely to become bent'or crumpled in handling the barrel.

It will be obvious that the reinforcing ribs 4 on the staves may beomitted if desired and. that, if thesereinforcing ribs are to be omitted, it will be unnecessary to out eases? staves as shown at 10 in Fig. 2. It will also be obvious that the head reinforcing spider 23 may be omitted if desired.
